Patent DE-2403035-A1 (DE)
Title: Integrated brake energy storage unit - has pressure storage bellows device to provide some vehicle reacceleration energy
Inventor: ERNST KARL AUGUST DR ING
IPC: B61H9/06
Filed: 1974-01-23
Abstract: The wheel axle is mechanically connected by pull rope to a compressor in such a manner that when a braking action is required the rope will pull the piston thereby causing a compression of between 100-300 atmospheric pressures to be stored. On release this is used to re-accelerate the vehicle when required via a coupling arrangement fitted to the rope drum shaft. The compressor cylinder wall thickness increases proportional to the pressure to be contained. the compressor piston has a flexible seal. A bellows may be used in place of the storage cylinders of the inner rear pneumatic tyre.

Title: Ninety-degree H-plane waveguide bend - has corner reflector of specified set-back to reduce insertion loss
Inventor: UNRAU UDO DIPL ING
IPC: H01P1/02
Filed: 1974-05-17
Abstract: The 90 deg. H-plane waveguide bend consists of a piece of rectangular waveguide bent through 90 deg. in the plane containing its larger faces. The corner so-formed has a 45 Deg. reflector (S) to reduce the bend's insertion loss. The reflector is set back from the actual corner by a distance d equal to 0.35a, where a is the width of the guide. The set-back reflector reduces miss-match and effectively increases the bend's bandwidth. Earlier types of bend with the reflector cutting straight across the corner, i.e. along the dotted line, give poorer matches.

Title: Stabilised front axle suspension - with transversely sprung damper pads to correct for braking irregularities
Inventor: BRAESS HANS-HERMANN DIPL ING D
IPC: B60G21/05

Title: Stomach pump with inflatable double wall at oesophagus - prevents inspiration of stomach contents into lungs
Inventor: CSIPKES JOSEF T DR MED
IPC: A61M3/02
Filed: 1974-12-03
Abstract: The tube (10) of the stomach pump which is fed in through the mouth and oesophagus into the stomach has a shutting device (20) in the oesophageal region closing off the intermediate space between it and the oesophageal wall thus preventing inspiration of stomach contents into lungs without the necessity of intubation. The shutting device (20) can consist of an expanding outer casing (20) coupled to a balloon pump (28) at the outer tube end with safety valve (30). The inflatable cuff (20) has several pre-formed, undulating sections (23). In use, the tube (10) is inserted into the oesophagus and once in place the outer casing section (20) is pumped up until the manometer (with the valve (30) closed) registers a positive pressure. The three preformed sections (23) expand until close contact is made with the oesophagus.
Patent DE-2508690-A1 (DE)
Title: Water consumption reducer for toilet cistern - uses small additional rods for a smaller amount of flush water
Inventor: SCHUERGER GERT
IPC: E03D1/14
Filed: 1975-02-28
Abstract: To save water when flushing the toilet, the amount of water used can be preselected by actuating the lever. The flush can also be manually interrupted, for the same purpose. The downward movement of the float rods during flushing is utilized to achieve a premature closing of the valve cone. Small additional rods are positioned above or on the valve cone, acting as a locking bolt for a 'small' amount of water. Premature turning of the flush lever, or an additional lever, causes the bolt end to be positioned below the valve rods. This causes the float to be braked during the downward movement of the float rods, causing the resulting pressure on the valve cone to press it downwards to prematurely seal the water outlet.

Title: Function generator for time dependent signal - has voltage dividers for generation of discrete signal amplitudes
Inventor: GLEIXNER FRANZ DIPL ING
IPC: H03K4/02
Filed: 1975-10-07
Abstract: Output signals of, possibly adjustable, voltage dividers are allocated to an odd signal amplitude. The voltage dividers are followed by a logic circuit controlled by a time control device. They connect to the function generator output sequentially in the order of odd and even signal amplitudes, either only one voltage divider, or at least two voltage dividers simultaneously through a mean value forming circuit. This arrangement doubles the number of signal amplitudes using the same number of voltage dividers as normally required. The accuracy of repeated output signals is increased.
